APPARATUS FOR WINDING THREAD ON SPOOLS.

SPECIFICATION forming part of Letters Patent No. 562,651, dated June 23, 1896.

Application filed February 15, 1895. Serial No. 538, l97. (N0 model.)

To all whom it may concern.-

Be it knownthat I, ISAAC E. PALMER, of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvem ent, in Apparatus for lVinding Thread on Spools, of which the following is a specification; J

The object of this invention is to provide for the automatic stopping of the spool when it becomes full, and to afford facility for the removal of the full spool from the winder-head, and, generally speaking, to enable the change of full spools for empty ones to be performed with as little handling as possible.

I will proceed to describe my invention with reference to the accompanying drawings, and afterward point out its novelty in claims.

Figure 1 represents a side view of a winden head embodying my invention. Fig. 2 represents a plan of the same; Fig. 3, a transverse section in the line 3 3 of Fig. 2 Fig. i, a back View corresponding with Fig. 1. Fig. 5 is a detail which will be hereinafter explained.

Similar letters of reference designate corresponding parts in all the figures.

All the movable parts of the winder-head herein represented are supported by a stand A B 0, consisting of a base A, on the ends of which are twostandards B B and two side plates 0 C. The side plates 0 O, which constitute a gage, as will be hereinafter explained, project forward beyond the standards 13 B. The said plates 0 O are so fitted to the standards B B as to be adjustable vertically thereon, and are slotted, as shown at o in Fig. 1, to receive screws a, which screw into the standards to secure the adjustment. The stand is supported on one of the girths G of the framing of the winder at a suitable distance from the drum or pulley by which the spool is driven. The said drum or pulley H and its shaft H are represented in Fig. 1, and a spool l is shown in dotted outline in Figs. 1, 2, and

In the standards 13 there is pivoted, by a pivot 12, a swinging spool-carrier. This spoolcarrier is represented as consisting of a swingin g frame D D and two independcntly-swinging arms E E, pivoted to the said swinging frame D D by a pivot cl and carrying the spool-spindle c.

The swinging frame I) D consists of two arms D and a connecting-bar D, A side view of this frame detached is given in Fig. 5. The pivot b passes through the two arms D of said frame, and the said frame is confined lengthwise between the standards 13, as may be understood by reference to Fig. 4..

The spindle-carrying arms E E are capable of swinging on their pivot d between a position in which both are supported on the bar D of the frame D D and positions in which they are separately supported by stops d d on the arms D of said frame. The spindlecarrying arms E E are represented as each made with two hubs c and f, which embrace the arms D between them, and the inner ends of the hubs f are constructed to form a clutch g, as shown in Figs. 2 and 4:. The hubs cf of the arm E are so spaced apart that the said arm is confined in place lengthwise of the pivot cl by its respective arm D of the frame D D. The hubs cf of the arm E are so spaced apart, as shown in Figs. 2 and 4, as to leave room between them and their respective arm D of the frame D D for a sufficient longitudinal movement of the said arm E on the said pivot d to clutch it with and unclutch it from the arm E. The spool-spindle c has one end fast in the arm E and its other end merely enters loosely into a bearing in the arm E. When the two arms E E are clutched together, the arm E receives its respective end of the spindle and a spool on the spindle is confined lengthwise thereon between the said arms, and when the arms are unclutched the arm E is withdrawn from the spindle. The arms E E when clutched are capable of being brought forward and dropping down between the said plates 0 and standards B, as shown in Figs. 1 and 2, and when in that position the arm E is so confined laterally by the adjacent standard or plate as to be kept clutched with the arm E, so that both move together about the pivots Z2 and (1, but when said arms are both raised up and thrown back to a position to clear the standards, as shown in dotted outline in Fig. 3, the arm E may move aside far enough to disengage it from the end of the spindle c, and when so dlSGl1 gaged it may drop back far enough to clear it from the end of a spool on the spindle and so permit the spool to be drawn off said spindle.

The pivots Z2 and cl and the gage-plates C are so arranged and the weight of the several.

parts-of the spool-carrier is so disposed that the spool-carrier has a tendency to swing backward automatically, as indicated in Fig. 3, when not restrained, as shown in Fig. l, by the projections i on the spool-carrying arms E E being in front of the gage-plates C. This tendency of the weight of the spool-carrier may be sufficient for the successful operation of the apparatus, but in order to assist in throwing it back I have represented (see Figs. 3 and 4) a spring J coiled around the pivot b and having one end bearing on the base A and the other end against the bar D of the swinging frame I) D. The backward-swinging movement is limited, as will be herein after more fully explained, by a stop (21*, consisting of a projection on one of the arms D, coming in contact with the base A, as shown in Fig. 3. The front edgesj of the gage-plates C are approximately vertical, being only slightly inclined forward,- as shown in Figs. 1 and 3, that the weight of the spool carrier and the throwing-back action of the spring upon it pulling the said arms against the said edges will exert a certain degree of downward pressure on the arms E E and thereby tend to press the spool into contact with the driving drum or pulley H. Stops ,7" for the arms E E are provided on the gage-plates 0 below the curved front edges j. The upper edges of the said plates 6 are approximately horizontal and are represented as having an up.-

ward inclination for some distance back from the front edges 3', as indicated at in Figs. 1 and 4'.

The operation of the device is as follows:

Then a spool is to be placed on the spindle c, the spool-carrier is swung back to a position in which the spindle-carrying arms E E are clear of the gage-plates C and the arm E is free to be moved aside on the pivot d to unclutcli it from the arm E. This position is indicated in Fig. 3 by the representation of the frame D D in full outline with its projection 61* stopped against the base A, and the representation of the arm E in dotted outline stopped against the stop (1 on said frame. The arm E is then moved aside and unther backward and downward until it is arrested by the stop 01 on the said frame, leaving room around the free end of the spindle c for the placing of the spool upon the latter.

proceeds, and as the quantity of thread on 1 in Fig. 3.

The end of the thread to be wound I the body of the spool increases the spool rises, the arms E E rising with it, until when the spool becomes full or has a desired quantity wound upon it the projections 11 of the arms E E rise clear above the abruptly-terminating front edges j of the gage-plates and leave the whole spool-carrier with the spool in it free to swing back by its weight aided by the action of the spring J, if the latter be used, until the stop (1* is arrested on the base A. hen this arrest takes place, the arms E E have passed the highest points on the top of the gage-plates G, as shown in full outline From this position they may be moved back by hand to the position shown in dotted outline in. Fig. 3, where they are arrested by the stop 61 on the frame D D, but if the spring J be used the momentum ac quired by the spool and its carryingarms will be sufficient to swing them back to the posi tion in which the arms are shown in dotted outline in Fig. 3. The arm E being now clear of its adjacent gage-plate O is free to be unclutched and dropped farther backward until arrested by the stop (1 on the frame I) D, in which position it is clear of the spool and permits the spool to be drawn off the spindle. An empty spool is then placed on the spindle, as hereinbefore described, and the arm E is again raised and moved into engagement withthe spindle and clutched with the arm E,and the spool-carrier and spool are then moved forward to allow the spool to drop into its operative position over the pulley or drum, as shown in Fig. 1.

It will be understood that the quantity of thread wound upon the spool is regulated by the height of the front edges j of the gageplates 0, which, consequently, constitute a gage to regulate the quantity of thread to be wound on the spool and to produce the automatic stoppage of the winding when such quantity has been wound. It is with a View to provide for a variation of the quantity to be wound that these gage-plates or gage are made separate from the standards B, and secured adj ustably thereto to be capable of being raised or lowered. clutched, and is then permitted to drop fur- I It may be here stated that the only object of thearm E is to steady the end of the spindle c. This arm E mayin some cases be dispensed with and in such case there will be a gage O on one side of the machine only. After the spool has been placed on the spindle, the arm E is returned to the position op- "What I claim as my invention is 1.
